Our Mission

JWA's Message
JWA's Message

We at the Japan Weather Association will exhibit foreseeability and creativity with a sincere and inquiring mind, and create “a society that is harmonized with the natural world,” together with a variety of people.

The JWA believes that “everything in this world is linked to weather, and our job is to contribute to the various sectors of this world.”
The “society that is harmonized with the natural world” as we see it is:

  • A society where natural threats are alleviated, and people can live safely and with peace of mind
  • A society where nature’s benefits can be drawn out and efficiently developed
  • A society where impacts on nature by social activities are minimized, and one can enjoy the greatness of nature

“Harmonability” is a keyword that the JWA created to easily express the activities of the JWA as a whole in aiming to create the kind of society described above. We are promoting our business in various sectors using the concept of “harmonability” as the axis.
